  • Flying object acceleration method by means of a rail-gun type two-stage accelerating apparatus
    Patent number: 5417140
    Abstract: In a two-stage railgun accelerating apparatus, a flying object is initially accelerated by acceleration gas produced by a gas gun. The initially accelerated flying object is led through an introducing pipe to an inlet of a railgun section of the two-stage railgun accelerating apparatus. A position and a velocity of the flying object are detected by a position detector and a velocity detector provided in the introducing pipe. According to the results of detection, both a voltage is applied to the railgun section and the acceleration gas is irradiated just behind the flying object with a laser beam, such that a dielectric breakdown of the gas is effected to generate plasma of good quality for accelerating the flying object.
    Type: Grant

    Date of Patent: May 23, 1995
    Assignee: Mitsubishi Jukogyo Kabushiki Kaisha
    Inventors: Masanori Onozuka, Yasushi Oda
